Abstract: Ride features described herein may include a ride surface in which a rider may be maintained on a lateral side wall while traversing the ride feature. The ride feature may be in a spiral to turn the rider about a central axis. The ride feature may include a central opening that provides a perception that the rider may fall off of the ride feature. The properties of the lateral side wall may be manipulated so that the centripetal force is used to control the rider's speed and position on the lateral sidewall so that the rider is kept away from the inside edge of the central opening. The centripetal force can be changed by: varying the pitch of the helix of the lateral side wall, varying the radius of the helix of the lateral side wall, varying the friction between the ride surface and the rider, and combinations thereof.
